Early last year the expected influx of patients with COVID-19 to emergency departments (ED) in New Zealand required rapid preparation.  Many questions needed answering quickly – such as, where will we put all the patients?

Apophis on a trip to down-town Auckland   On Friday night, 5 March 2021, the “God of Chaos” sped past our planet. The asteroid Apophis, or “God of Chaos” as it is known, made a close approach.  Bigger than the Sky Tower (about 370m diameter) and faster than a speeding bullet (4 km/s or about 14,000 km/h) it would surely … Read More

• Heart Attack,
• machine learning,
• Myocardial Infarction

“Machine learning” rates very high on the buzz-word scale, right up there with “nano-technology” and “blockchain”. Like most buzz it is more noise than substance. However, every now and again it looks like there might be something in the noise that bites. This episode of the Cheesecake Files1 is about testing an algorithm (another buzz word) developed through a … Read More

Dark space

Dark space, like green space, is essential for our well being. Dark space, like green space, is our past, our taonga, and our right. Dark space, unlike green space, is not prioritised in our city plans, is not part of our conversation about Te Tiriti, nor is it where we go for relaxation and inspiration. But once it was.

Am I doing what the public thinks is OK to do?   That was the question that came to mind as I heard Bioethics and Health Law expert Rochelle Style speak at a Health data workshop held at the University of Otago Christchurch this week.  Rochelle spoke with clarity and demonstrated a great deal of expertise.  I like the simplicity of Law – tells … Read More

Dear Driver, When you backed out of a driveway and did not even see how I swerved around behind your car to avoid T-boning you, how dare you have the temerity to tell me you were careful!  I was 7 feet tall, dressed in bright yellow and traveling at no more than 10 km/h.  Perhaps a simple lesson in physics … Read More

Your chest hurts, you go to the hospital (good move), you get rushed through and a nurse takes some blood and measures the electrical activity of your heart.  A doctor asks you some questions.  While she does so, the blood is being tested – the results are back already! Yeah, they are negative and everything else is OK, it’s not a … Read More
